Hi,
I'd like to ask if it possible to change "data" field (its content) in TCP
packet on fly? I don't need to change data's lenght but only change few bytes
in it.
Example:
0000 ff ff ff ff ff ff 00 11 25 31 ad e0 08 00 45 00 ........%1....E.
0010 00 c1 0a b1 00 00 80 11 82 0f ac 13 01 59 ff ff .............Y..
0020 ff ff 04 2d 01 db 00 ad 60 78 ad a7 5b de 9f 26 ...-....`x..[..&
0030 ec 98 2d 26 ec 18 2d 26 ec 18 2d 26 ec 18 2d 26 ..-&..-&..-&..-&
0040 ec 18 2d 26 ec 18 2d 26 ec 18 2d 26 ec 18 2d 26 ..-&..-&..-&..-&
First line contains MAC address 00:11:25:31:ad:e0 - I need to change it to
other value.
Is it possible at all?
Marcin
